7-15What is Precast Refractory Shapes ?
The Precast Refractory Shapes is the category of irregular refractory materials, also known as the prefabricated block of the pouring materials, and the irregular refractory prefabricated block. It is to pour the mixed castable. Most of the castable materials can be tightly arranged and full of models in the mixed material by only pouring or vibrating, and they can be poured into the desired shape through the mold. Therefore, it is more flexible to make Precast Refractory Shapes, with a variety of shapes and excellent performance.
Types of Precast Refractory Shapes：
There are many types of Precast Refractory Shapes. According to the variety of ingredients, prefabricated parts such as clay, high aluminum, carbonized silicon, and rigidity can be divided into prefabricated parts. , Small prefabricated parts; some prefabricated parts with reinforced and anchoring parts can also be divided into ordinary prefabricated parts, reinforced prefabricated parts, and anchor prefabricated blocks.

Baking of Precast Refractory Shapes：
As a producer of Precast Refractory Shapes, we have many years of production experience. When the refractory prefabricated parts are placed in the lining and furnace body of the thermal equipment, it should generally be baked before the first use, so that the physical water and the physical water and the physical water and the inhabited in it should Crystal water is gradually eliminated, so that its volume and certain performance can reach the stable state during use, and to a certain degree of sintering. Whether the sintering system is correct has a great impact on the service life.
The basic principle of formulating the baking system is that the heating speed should be compatible with possible dehydration and other object changes and deformation. In some temperature stages of the above -mentioned changes, slowly heating or even thermal insulation should be slowly heating. If it is not baked properly or without baking, it is quickly invested and put into use immediately, which is prone to severe cracks and even loose collapse, and may even explode in the extraordinary thickness part. The baking speed of the hardening vary depending on the size of the binding agent and the structure of the structure. In terms of cement pouring, it can be roughly divided into three stages:
(1) Dowry free water. Heat at 10-20 ℃ H to 110-115 ° C 24-48h.
(2) Eliminate crystal water. Heating at 15 ～ 30 ℃ / h to 350 ° C, and thermal insulation is 24-48h.
(3) The average heat stage. Heat at 15-20 ° C / h to 600 ° C, and thermal insulation is 16-32h. Then heat up at 20-40 ° C / h to the working temperature. The heating speed of the large section of the structure is reduced, the upper limit is taken for the insulation, and the small one is the opposite.

Advantages of Precast Refractory Shapes:
1). Without the shape of the use site, the characteristics of refractory materials can be realized. (The shape of individual parts of the kiln cannot achieve refractory brick masonry, and the Precast Refractory Shapes make up for this deficiency.)
2). The material performance is superior, and the product has a longer service life. (You can choose the raw material of Precast Refractory Shapes according to the location and working temperature of the use of the equipment.)
3). Construction convenient and fast installation. (The production of the Precast Refractory Shapes is carried out by the supplier, which has completed several links such as pouring, maintenance, and drying in advance to reduce the construction time on the spot. It also solves the problem of explosion caused by the rapid heating of the kiln.)
4). It can be installed at any time without restrictions on ambient temperature. (The early work of Precast Refractory Shapes has been completed by the supplier. After receiving the goods, it can be installed and used directly, which can be constructed in any season.)
In recent years, Precast Refractory Shapes has been widely used in heat work equipment such as heating furnace, electric furnace top, steel grooves, and fire -spraying mouths, and play a large role. It is an important development direction in the future.
Maintenance suggestions for Precast Refractory Shapes suppliers:
After the pouring is forming, appropriate measures must be adopted according to the hardening characteristics of the binding agent to promote hardening. Calcium aluminum cement should be maintained at appropriate temperature and humid conditions. Among them, ordinary high aluminum cement should be covered at a lower (less than 35 ° C) temperature. 7 days, or steam maintenance 24h. Dry and bake for certain metal inorganic salts. If the water glass is combined, it should be stored in the air for 3-5 days at 15-25 ° C. It is not allowed to be wet, or it can be baked below 300 ° C. However, it must not be maintained under humid conditions, and it is not allowed to water. Because the silicon gel absorbs water and swells, loses adhesion, and after the water dissolves, the intensity is more sharply reduced. Those with phosphate can be maintained in the air above 20 ° C for more than 3 days, and then baked through 350 to 450 ° C. Before baking, it is not allowed to be moisture and dipping.

High alumina brick is one of the indispensable basic refractory materials in the upper and middle parts of blast furnace body in iron and steel industry
Common low-creep high-alumina bricks can be used in blast furnace hot blast stoves, as well as other industrial kilns, and can also be made into low-creep high-alumina bricks of different sizes according to specific construction requirements, such as lattice bricks, special-shaped bricks, anchor bricks, etc. , mainly used in industrial kilns in long-term high temperature environments
high alumina refractory bricks is mainly used around the furnace cover, electrode holes and exhaust holes of electric furnaces, and its service life is 1 to 2 times longer than that of silica bricks.
Insulating high alumina refractory bricks mainly refer to refractory products with an aluminum content of more than 48%. They are also called lightweight high-alumina bricks or heat-insulating high-alumina bricks due to their advantages of low bulk density, light weight, and good heat insulation effect. . It is a kind of thermal insulation refractory brick commonly used in high temperature industrial kilns and thermal equipment.
Magnesia alumina bricks use periclase as the main crystal phase and magnesia-alumina spinel as the matrix. They are better in thermal shock resistance than magnesia bricks. In order to improve the thermal shock resistance of magnesia bricks, alumina or alumina is introduced into the ingredients. Bauxite clinker fine powder to form a magnesia-alumina sharp stone matrix, thereby making magnesia-alumina bricks
Magnesia chrome bricks are refractory products with magnesia (MgO) and chromium trioxide (Cr2O3) as the main components, and periclase and spinel as the main mineral components. The main raw materials for the manufacture of magnesia-chrome bricks are sintered magnesia and chromite.
Anti stripping high alumina bricks are referred to as anti-stripping bricks or anti-stripping refractory bricks. Anti-stripping high-alumina bricks are widely used in my country's new dry process kiln, Libore kiln and wet process kiln, including kiln door cover, rising flue, cooling zone, decomposition zone, safety belt, transition zone, coolant rear Walls and side walls and beams with curved ceilings.
Yuying Refractory produces a complete set of refractories for electrolyzers, and the new impermeable bricks are used in conjunction with impermeable castables
