Abstract
The utility model relates to the field of fire-resistant material in a cement industry, in particular to a precast part used for a decomposition furnace cone and a smoke chamber slope. The precast part comprises a precast brick body which is in a trapezoidal structure, and two heads of the trapezoid are a large head and a small head of the precast brick body. The precast part is suitable for parts, such as the decomposition cone, a smoke chamber and the smoke chamber slope of a novel dry-process cement rotary kiln and is directly constructed, construction and maintenance are convenient, the precast part is safe and reliable, and construction period is shortened greatly. In addition, the precast brick body is made of special silicon carbide anti-crusting material, the service life is long, strength is high, and the precast brick body is high-temperature-resistant, wear-resistant, wear-resistant and anti-crusting and has excellent anti-crusting performance and alkali-corrosion resistance, and the smooth brick surface is favorable for slipping of crust.
Description
Technical field:
The utility model relates to the cement industry fire resisting material field, in particular, relates to a kind of dore furnace centrum and smoke-box slope and uses prefabricated component, is applicable to positions such as new type nonaqueous cement rotary kiln dore furnace centrum, smoke-box, smoke-box slope.
Background technology:
Dore furnace centrum position, smoke-box and position, smoke-box slope are often because temperature is too high, raw ingredients changes greatly; Ature of coal is poor, sulfur content is high, incomplete or the like the reason of coal dust firing causes skinning; But consider from the refractory material aspect; One of them reason of skinning is exactly the refractory material wearing and tearing out-of-flatness at dore furnace centrum position, smoke-box and position, smoke-box slope, causes bridging, and skinning the lighter available air big gun is removed and the labor cleaning; Increased workman's working strength like this, also caused to stop kiln when serious and clear up.Run well for guaranteeing to produce, these positions must be selected suitable material for use.
The utility model content:
The purpose of the utility model is the weak point to prior art, provides a kind of dore furnace centrum and smoke-box slope to use prefabricated component, and it cancels original heat resisting steel nail and pours cast, adopts preformed bricks directly to build by laying bricks or stones, construction, and it is easy to maintenance, and is safe and reliable.
The technological solution of the utility model is following:
Prefabricated component is used on dore furnace centrum and smoke-box slope, comprises the preformed bricks body, and said preformed bricks body is a trapezium structure, and two of product is the concentric reducer of preformed bricks body.
The beneficial effect of the utility model is:
The preformed bricks of the utility model, compact structure, surfacing, smooth has good anti-scaling property and alkali resistant erosion performance, helps the landing of skinning.It is directly built by laying bricks or stones, constructs, and is easy to maintenance, safe and reliable, has shortened the construction period greatly, the cancellation of heat resisting steel palladium nail also in various degree reduction Master Cost, improved overall economic efficiency.
The material of the preformed bricks of the utility model is the silicon carbide crusting resistant special material, long service life, and its intensity is high, and is high temperature resistant, wear-resistant, the resistive connection skin.General skinning not during use even very fraction skinning occurs, also as long as clear up and will drop with tracheae, has both alleviated workman's working strength, has shortened rotary kiln again and has cleared up stopping the kiln time of skinning because of ending material.The utility model can be processed different size according to requirement of client simultaneously, satisfies client's demand.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is done further explanation:
Fig. 1 is the structural representation of the utility model.
The specific embodiment:
The following stated is merely the preferred embodiment of the utility model, is not that scope to the utility model limits.
Embodiment sees accompanying drawing 1, and prefabricated component is used on dore furnace centrum and smoke-box slope; Comprise preformed bricks body 1, said preformed bricks body is a trapezium structure, and two of product is the concentric reducer of preformed bricks body; Its compact structure, surfacing, smooth helps the landing of skinning.
Claims (1)
1. prefabricated component is used on dore furnace centrum and smoke-box slope, it is characterized in that: piled up by the preformed bricks body and form, said preformed bricks body is a trapezium structure; And two of trapezium structure is the concentric reducer of preformed bricks body.
