Description
Technical field
The utility model relates to a kind of roller kilns carborundum plate, particularly relates to a kind of alumina balls roller kilns carborundum plate, belongs to fine ceramics product technique field.
Background technology
Alumina balls are mainly used in the abrasive media of ceramic raw material, and firing of alumina balls generally adopts tunnel cave, along with the progress of technology, now progressively develop into and burn till with roller kilns.Roller kilns are kilns of continuous burnt, using the backing plate on live-rollers rod as base substrate delivery vehicle.Be exactly that ceramic product (alumina balls) is placed on backing plate specifically, backing plate is placed on the very close horizontal refractory roll rod in many bar intervals, and the rotation of roller rest rod makes ceramic be sent to kiln tail from kiln hood, simultaneously shaping by high-temperature firing.Therefore the roller in roller kilns is excellent and all necessary intensity of backing plate is high, high temperature resistant and wear-resisting.Alumina balls easily roll, and backing plate surrounding must be provided with frame, ensure that alumina balls no longer do not drop in sintering procedure.The large multiplex mullite synthesizing-cordierite backing plate of backing plate that existing roller kilns use in using, bearing capacity is more weak, and is easily out of shape, and anti-wear performance is not good, and access times are less, and large to kiln furnitures consumption, use cost is higher, and product quality is not ideal enough.
Summary of the invention
The purpose of this utility model is that the backing plate bearing capacity used in using for existing roller kilns is more weak, in use easily be out of shape, resistance to elevated temperatures and antioxygenic property are not good, the defect that service life is shorter and deficiency, there is provided a kind of bearing capacity strong, in use can not be out of shape, resistance to elevated temperatures and antioxygenic property good, thermal coefficient of expansion is low, a kind of alumina balls roller kilns carborundum plate of long service life.
For achieving the above object, technical solution of the present utility model is: a kind of alumina balls roller kilns carborundum plate, comprise plate body, the rectangular flat that described plate body adopts carborundum to make, the surrounding integrated setting of plate body has frame, frame forms edge chimb at the upper surface of plate body, and the bottom of plate body is provided with the reinforcement of grid type.
The side of described plate body offers respectively the expansion joint running through frame and reinforcement, the length at expansion joint is the 1/8-1/4 of plate body along length on the bearing of trend of expansion joint.
Described plate body, frame and reinforcement are silicon nitride combined silicon carbide pottery, adopt silicon carbide sand, metallic silicon power, micropowder bonded agent, rare metal additive and glue to be that material is made.
The grid that described reinforcement is formed is rectangle or rhombus, and the cross section of reinforcement is trapezoidal.
The beneficial effects of the utility model are:
1, the utility model adopts carborundum to make rectangular flat, the surrounding integrated setting of plate body has frame, alumina balls can not fall down from the upper surface of plate body in sintering procedure, the bottom of plate body is provided with the reinforcement of grid type, improve the intensity of plate body and reduce roller-way resistance, the side of plate body offers expansion joint respectively, effectively reduces the utility model and using the probability occurring breakage.
2, the utility model intensity in hot environment is high, bearing capacity is strong, in use can not be out of shape, resistance to elevated temperatures and antioxygenic property good, thermal coefficient of expansion is low, can bear the adverse circumstances of heating and cooling repeatedly, can not be out of shape in use procedure, substantially prolongs service life, and improve finished product rate, stabilize product quality.
