  B. product introduction;

This paper provides a preparation method for graphite lining for ore hot furnace. This method solves the problems of short service life, corrosion resistance and poor wear resistance of refractory lining in ore hot furnace in existing technology. Preparation method of graphite lining for ore hot furnace, which includes the following steps: 1) preparation: raw material, by weight, is composed of: 75 ~ 84 percent after petroleum coke, 16 ~ 25% after coal is gradually green;

 2) mixing and kneading: mix and mix the prepared raw materials in a dry and wet way;  

3) shock material: the paste treated with mixed paste is poured into the molding container, and the paste is divided into 2 ~ 3 times from the opening of the molding container through the press, the pressure of 6 ~ 12mpa is compacted, the pressure of 6 ~ 5mpa, and the vibration and pressure pressure is 6 ~ 12mpa;  5) - secondary loss: put the pressed burning products into the burning furnace for one loss;  6) leaching; Put a burn in the leaching tank, in the condition of keeping vacuum and pressure, inject into the leaching agent gradually green for leaching treatment, so that the leaching agent gradually green into the primary burn;  7) second loss: put the leaching product into the burning furnace for the second loss;  8) graphitization: put the secondary loss products into graphitization furnace. In the case of isolation of air, add the purified gas, so that the cost loss products can be heated to 2300 ~ 3000c for graphitization, and obtain graphitization;  Mechanical processing: the graphite lining used in the furnace is obtained by mechanical processing of graphitized products
