A production device and process of high -temperature magnesium carbon brick

Abstract

The invention discloses a high-temperature-resistant magnesia-carbon brick production device and its process. In the invention, the magnesia-carbon brick raw material is put into a pressing mold box, and the magnesia-carbon brick embryo is obtained by machine pressing, and the refractory coating is applied on the On the fire-facing surface of the magnesia-carbon brick embryo, specifically, the pressing mold box is rotated 90 degrees and aligned with the vertical discharge box, and the cylinder is driven to simultaneously push the mold box bottom plate and the coating roller out, and the mold box bottom plate pushes the magnesia-carbon brick embryo into the vertical discharge box, and the coating roller just smears the refractory coating on the fire-facing surface of the magnesia-carbon brick embryo during the process of moving and resetting the pressing mold box; The whole process of roasting avoids manual or machine contact with the surface of the magnesia-carbon brick embryo, which improves the quality of the magnesia-carbon brick embryo.

Description

technical field [0001] The invention belongs to the technical field of refractory material production, and specifically relates to a production device and process for high-temperature resistant magnesia-carbon bricks. Background technique [0002] Magnesia carbon brick, commonly known as refractory brick, is a refractory material made of refractory clay or other refractory raw materials. It is mainly used for building smelting furnaces. It can withstand high temperatures of 1580°C-1770°C. It is a refractory material with a certain shape and size. It can be used as high-temperature building materials and structural materials for building kilns and various thermal equipment, and can withstand various physical and chemical changes and mechanical actions at high temperatures. Magnesia-carbon bricks contain graphite that is easily oxidized at high temperatures and binder phenolic resin After baking at 800-1100°C, carbon oxidation will inevitably occur and an obvious decarburizati...

Problems solved by technology

[0003] In the high temperature working environment, the fire-facing surface of magnesia-carbon bricks is most affected. At present, the most convenient measure to improve this situation is to coat the fire-facing surface of magnesia-carbon bricks with a refractory layer, but the existing production processes are all The material is coated after the magnesia-carbon brick is fired, and the bonding performance between the refractory layer and the magnesia-carbon brick matrix is ​​not very good. In addition, the existing production equipment is various and the process is complicated, which affects production efficiency.
