Use of metering nozzle

Use of metering nozzle

The metering nozzle is one of the refractory materials for billet continuous casting, and it plays the role of controlling the flow of molten steel. The molten steel flows into the mold through the metering nozzle at a constant speed and stably, which is a necessary condition to ensure the normal operation of continuous casting. As a flow control element, the tundish metering nozzle should have good anti-scour and anti-erosion capabilities. During use, the inner diameter should not expand too quickly. Once the expansion size of the metering nozzle exceeds the allowable range of the mold pulling speed, it means the sizing The nozzle has been seriously damaged and cannot be used any longer. The expansion of the metering nozzle has become a bottleneck problem in the study of improving the life of the tundish.

What are the types of heat insulation refractory materials

Thermal insulation refractory can also be called lightweight refractory, and is also often called thermal insulation material. It is widely used in the insulation layer of industrial kiln. There are many varieties and classifications of heat insulation and refractory materials. There are light clay bricks, light silica bricks, light high alumina bricks, mullite poly light bricks, alumina hollow ball bricks, high alumina poly light bricks, etc. Light brick has stable performance and convenient use, transportation and storage. According to the temperature classification, the insulation refractory materials are divided into low temperature insulation materials (< 600 Celsius), medium temperature insulation materials (600 ~ 1200 Celsius) and high temperature insulation materials (> 1200 Celsius). In terms of bulk density, the bulk density of commonly used lightweight insulation refractory materials is 1.0 ~ 1.2 g/cm3, and 0.3 ~ 0.6 g/cm3 is called ultra-lightweight insulation materia

Application of low thermal conductivity MgO-C bricks in ladle

图片
Magnesia Carbon Brick Currently, inhibition of steel temperature droping has become a major issue for many steel plants. Therefore, in order to suppress temperature drop of molten steel, there has a test to study insulation problem of refractory material lining in 185t ladle, by comparing three different measures. Measure 1: Reducing the heat transfer effect of sidewall castables (30% reduction). This method is by reducing coarse particles in castable, increasing porosity and other measures to reduce the thermal conductivity, to suppress heat dissipation. Measure 2: Using insulation materials in the backlayer of wall castable. This method is to use one layer insulating refractory bricks with less than 1W (m celsius) thermal conductivity between ladle steel shell and wall castable, to inhibit heat dissipationheat. Measure 3: Reducing the heat transfer of slag line magnesia carbon brick heat transfer (30% reduction). This method is developed in recent years, to select
