Introduction of forging

La forja es un proceso metalúrgico necesario que juega un papel vital en la fabricación de varias piezas y componentes.. Bajo altas temperaturas, alta presión, y duras condiciones de trabajo, refractory materials are the key to ensuring the stable forging process. This article will introduce several joint forging refractory materials and their application in the forging process.

Forging furnace requirements for refractories

  1. It should have the property of not deforming and not melting under sufficient temperature
  2. It can have the necessary structural strength at high temperatures without softening deformation
  3. The volume is stable at high temperatures, and the brickwork will not be deformed or cracked due to expansion and contraction
  4. When the temperature changes sharply or the heating is uneven, it will not crack and peel off
  5. Can resist the chemical erosion of metal solution, slag, furnace gas, etc..

What are the refractory materials in the forging industry?

Refractory brick

In forging furnaces and heating furnaces, ladrillos refractarios are widely used as lining materials to protect furnace structures from high temperatures and molten metal corrosion. The main refractory bricks used are ladrillos refractarios con alto contenido de alúmina, aluminum silicate refractory bricks, y ladrillos refractarios de carburo de silicio.
