Brief Introduction:

 

In order to meet the need of the rapid development of high-temperature industrial,our factory research and develop blowing argon guns,ladle blowing agron air brick and so on under the guidance of the domestic first-class level refractory experts. Now a series of products has formed to meet different user's needs,also promote to apply among many still mills and highly praised.We can provide a variety of amorphous bulk refractories, precast blocks accroding to the customer's request. Customer first and quality first,we look forward to cooperate with you.
