Ladle Nozzle Well Block

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

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.

Magnesia Alumina Carbon Brick, Alumina Magnesia Carbon Brick

Introduction

Changxing Refractory's Alumina Magnesia Carbon Brick is made from high quality bauxite, corundum and fused magnesia. The Alumina Magnesia Carbon Brick is formulated with very high purity alumina and magnesia, it is mainly used for ladle side wall and bottom. Alumina magnesia Carbon Brick holds better anti-strip advantages than magnesia carbon brick in ladle. Changxing Refractory will design different brand Alumina Magnesia Carbon Bricks according to your ladle type and molten steel type, and providing optimal performance at the lowest possible cost.

Alumina Magnesia Carbon Bricks is made from high quality bauxite, corundum and fused magnesia. It is formulated with very high purity alumina and magnesia.
Advantages

It has low thermal conductivity, good isolation ability, and appropriate residual expansion
Application

Alumina Magnesia Carbon Bricks are used in Ladle Sidewall and Bottom impact areas.

Continuous use of functional refractories

refractory material

With the development of continuous casting, the proportion of high-clean steel production increased, the sliding nozzle with a skateboard, long nozzle, the water inlet, the inlet, immersion nozzle and other flow control and blowing function of the need for a sharp increase in refractory materials. In contrast to the earlier use of imported bricks, such as the use of imported bricks, continuous casting refractory material are still dominated by domestic production of products.
Sliding with a skateboard, mainly the use of aluminum carbon, and later, due to improved materials, the use of improved conditions, greatly improved the number of durable. Material, due to the addition of zirconia, peeling resistance greatly improved. According to the experimental and stress calculation, the shape of the skateboard is improved, which suppresses the generation and expansion of the crack. Due to the miniaturization of the skateboard and the re-use of the rear skateboard, the consumption of the refractory brick is reduced, so that the iron making is propelled. On the other hand, the development of high-corrosive steel slabs such as Ca-treated steel and high-carbon steels has been developed. For example, an aluminum-magnesium carbon alkaline skateboard having both corrosion resistance and peeling resistance has been developed.
Long water nozzle is the most recent 10 years to improve the maximum refractory products, recently, long water mouth life can reach 30 furnace or 40 furnace is not surprising. Preheating, insulation and residue cleaning and other aspects of the use of improvements, for the extension of life has a significant effect. Material, the measures taken to strengthen the strength of the bowl material, to suppress the wear of the inner tube, to prevent external oxidation and to prevent peeling.
Submerged entry nozzle, its characteristics and the flow pattern within the mold and the relationship between the quality of slab larger, it is generally from the material and shape of the two aspects of development and improvement. Material development is representative of the nozzle inside the alumina difficult to attach the development of materials. Generally use ZrO2-CaO-C material, the recent widespread use of carbon-free lining. Shape of the development, there are ladder-type immersion nozzle, this nozzle can effectively prevent the bias current, reduce the nozzle inside the alumina adhesion. In addition, a scheme for the use of a swirling flow nozzle and a vortex flow nozzle with spherical protrusions is proposed, and a furnace test is underway.

Steel Flow Initiator---refractory castable---Changxing Refractory

Steel flow initiator is a kind of ladle slid nozzle filler which is successfully developed by our company in recent years, results show that ladle castables success rate of automatic start casting can reach above 95 percent. 

Steel Flow Initiator

Introduction:
Steel flow initiator is a kind of ladle slid nozzle filler which is successfully developed by our company in recent years, results show that ladle castables success rate of automatic start casting can reach above 95 percent. There is no metallic inclusion in ingot surface, is a kind of ideal ladle slide nozzle filler. Steel flow initiator contains metal mixture whose weight is heavier and melting point is lower than molten steel. Before pouring we put it into upper nozzle, using it to burning and causing the molten steel within the upper nozzle will not be solidified, to achieve the purpose of automatic start casting and avoid the problem of ingot inclusions.
