Trapezoid-groove refractory brick

Abstract

The invention belongs to the field of kiln refractory materials, and particularly discloses a trapezoid-groove refractory brick. When the refractory brick is horizontally arranged, a first protruding block is arranged on the upper surface, a first groove matched with the first protruding block in shape and size is formed in the lower surface, and the first protruding block and the first groove are located on the same vertical line; and a second protruding block is arranged on the right surface, a second groove matched with the second protruding block in shape and size is formed in the left surface, and the second protruding block and the second groove are located on the same horizontal line. When the refractory bricks are spliced, errors are small.

Description

technical field [0001] The invention relates to the field of kiln refractory materials, in particular to a trapezoidal groove refractory brick. Background technique [0002] TC bearings are the core components of screw drilling tools and need to have high wear resistance, so the requirements for their hardness are more stringent during the manufacturing process. At present, the manufacturing of TC bearings is mainly carried out in a sintering furnace. The fired TC bearings are first placed on the refractory bricks on the workpiece car, and then the workpiece car is pushed into the sintering furnace. [0003] At present, the kiln is built by splicing and stacking some standard refractory bricks. Since the shape of the standard refractory brick is a cuboid, it is necessary to cut the standard refractory brick according to the shape and size of the kiln before stacking the kiln. In order to achieve the purpose of stacking the kiln, especially for the refractory bricks used at ...

Problems solved by technology

[0003] At present, the kiln is built by splicing and stacking some standard refractory bricks. Since the shape of the standard refractory brick is a cuboid, it is necessary to cut the standard refractory brick according to the shape and size of the kiln before stacking the kiln. In order to achieve the purpose of stacking the kiln, especially for the refractory bricks used at the bottom of the kiln, during the cutting process, it is necessary to accurately splice multiple standard refractory bricks first, and then cut all the refractory bricks as a whole after splicing. Since the refractory bricks are all standard cuboids, and the refractory bricks are heavy, splicing is very difficult. If the splicing error is large, it will also affect the cutting
