1.Choose the right timing. The first repair should be after 60-70 heats or when tapping time is no more than 2 minutes and 10 seconds, then repair after each 30-40 heats.
2.Incline the EAF after tapping, properly place the gunning sleeve in the taphole through sand filling hole.
3.Mount pallet on EBT handcart.
4.Mount nut cap on gunning sleeve.
5.Get the gunning mix ready on EBT platform.
6.Put the gunning head into sand filling hole to spry the gunning refractory material into the gap between gunning sleeve and taphole refractory bricks.
7.Close the gunning machine and pull out gunning head when the gunning material is in the same level with bottom material.
8.Dismount nut cap and pallet.

Ladle Nozzle Well Block
Ladle Nozzle Well Block
Introduction
The ladle nozzle well block connects the wearing refractory lining of the ladle bottom to the mechanism or ladle gate for the flow control. To the well block is asked a huge wearing resistance and moreover it has to protect the nozzle placed inside it. Our ladle nozzle well block is made with magnesia carbon material or alumina carbon material, which can be made according to customized.
The ladle nozzle well block can be realized in any size and shape and strengthened with steel fibers to improve its mechanical resistance.
The series of well blocks for nozzles are made from high-purity, high-density, high-strength materials. Based on different materials, they have corundum, magnesia carbon and alumina spinel carbon.
Advantages
They show the features of stable structure, excellent thermal shock resistance, good corrosion/erosion resistance and long service life.
Application
It is mainly used to fix upper nozzle in steelmaking.

Low Carbon Brick and Carbon-free Brick
Low Carbon Brick and Carbon-free Brick
Introduction
Low carbon magnesia carbon brick using with crystal magnesite, fused corundum, fused spinel, high purity and ultrafine graphite and nano composite antioxidant as raw materials, which are used for ladle slag line. Low carbon and carbon-free corundum spinel bricks are used for ladle lining and bottom. It can realize ladle low carbon and carbon-free to meet the needs of high grade and ultra-clean steel. The products are characterized by corrosion resistance, penetration resistance, erosion resistance, spalling resistance and good integrity, to meet the need of complete refining ladle. It is the leading level in the domestic.
Advantages
In order to solve the problems of thermal transmission of the ladle and carbon raising in molten steel, low carbon brick and carbon-free brick have been developed and are beneficial for improving steel quality.
Application
Low Carbon Brick and Carbon-Free Brick are applied to refining ladle for making mild steel, super low carbon steel and stainless steel.
