What are the precautions for making magnesia carbon brick in ladle?

Ladle magnesian carbon brick has high temperature resistance, good thermal shock stability, corrosion resistance, resistance to spalling, the following to share the ladle magnesian carbon brick brick precautions are what?

1. Strictly control the measuring tools when batching, and prohibit moisture and caking of the raw materials used.

2, mixing needs to be added in order, such as: magnesia aggregate - phenolic resin binder - graphite - powder and additives

3, forming according to the first light after the heavy, multiple pressure process, the hanging billet is required to 2-3 times, full exhaust, so as to avoid spalling.

4, in order to control the low temperature strength of magnesium carbon brick, it is necessary to strictly require the heat treatment temperature and heat treatment time suitable for the binder. Usually the phenolic resin binder needs enough time and temperature when it reaches the curing temperature, so the heat treatment time and heat temperature need to be strictly controlled.
