Heat-resistant structures for kiln cars in tunnel kilns

Abstract

The invention discloses a heat-resistant structure for a tunnel kiln car, and relates to a kiln car heat-resistant structure. The heat-resistant structure comprises a convex coaming plate, a concave coaming plate, side coaming plates, front coaming plates and back coaming plates; the convex coaming plate and the side coaming plates are connected through coaming plate channel steel, the concave coaming plate and the side coaming plates are connected through coaming plate channel steel, and the coaming plate channel steel is fixed to a frame of the kiln car; a convex coaming plate convex plate is arranged at the upper end of the face, far away from the kiln car, of the convex coaming plate, and a concave coaming plate convex plate is arranged at the upper end of the face, close to the kiln car, of the concave coaming plate; side coaming plate convex plates are arranged at the upper ends of the faces, far away from the kiln car, of the side coaming plate; front coaming plate convex platesare arranged at the upper ends of the faces, far away from the kiln car, of the front coaming plates, and back coaming plate convex plates are arranged at the lower ends of the faces, far away from the kiln car, of the back coaming plates; and heat-resistant cotton, earth and red bricks are sequentially laid on the upper surface of the kiln car from bottom to top. According to the heat-resistantstructure for the tunnel kiln car, the service life of the kiln car is significantly prolonged, the manufacture cost and the maintenance cost of the kiln car are significantly reduced, refractory bricks are replaced with the earth and the red bricks, and almost no maintenance cost is generated.

Description

technical field [0001] The invention relates to a heat-resistant structure of a kiln car, more specifically it is a heat-resistant structure for a tunnel kiln car. Background technique [0002] The existing kiln car is covered with refractory bricks on the kiln car. The refractory bricks are directly placed on the kiln car and exposed outside the kiln car. They are easy to break and fall off. Brick and tile factories spend a lot of money on repairs every year, and the price of refractory bricks is high. , The investment in new brick and tile factories is high. [0003] Therefore, developing a heat-resistant structure for tunnel kiln cars has become an urgent and important task. Contents of the invention [0004] The object of the present invention is to provide a heat-resistant structure for a tunnel kiln car in order to overcome the disadvantages of the above-mentioned background technology. [0005] In order to achieve the above object, the technical solution of the pr...
