Lining pouring method for telescopic moulding bed and used for integral pouring for lining of molten steel tank

Abstract

The invention discloses a lining pouring method for a telescopic moulding bed and used for integral pouring for a lining of a molten steel tank, and relates to the technical field of construction methods for castables of molten steel tanks. According to the lining pouring method for the telescopic moulding bed and used for integral pouring for the lining of the molten steel tank, a frame and a shell body of the molding bed are integrally connected and have different functions, the relative displacement of the frame and the shell body is realized by using the thrust of an electric cylinder, and the purpose of accurate centering is achieved; the shell body of the moulding bed is divided into two parts, that is, a telescopic door and the shell body, the telescopic door is moved through the thrust of an electric push rod, the working diameter of the shell body of the moulding bed is changed, and a shaping pouring function and a demoulding function for the moulding bed are realized; and attached vibration motors which are arranged in a layered and staggered manner are adopted, so that uniform and independent vibration of all parts of the moulding bed is ensured, and the compactness of a castable is realized.

Description

technical field [0001] The invention relates to the technical field of construction methods for castables for molten steel tanks, in particular to a method for pouring inner linings of stretchable membranes for integral casting of inner linings of molten steel tanks. Background technique [0002] With the development of monolithic refractory materials, the application of castables in the lining of molten steel tanks is becoming more and more extensive. The biggest problem in the application of castables is the construction problem. Due to temperature and humidity changes, raw material quality, construction methods and other uncertain factors, they will have a great impact on the construction process and performance of castables, which will cause construction problems. Interruption, waste of materials, and even steel breakout accidents during use. [0003] The tire mold is generally used for the construction of the castable. The tire mold is a circular platform with a large ...
