Example Embodiment

[0032] Such as figure 1 , figure 2 As shown, the explosive welding manufacturing process of the continuous casting roll of the present invention includes the following steps:

[0033] Step 1. Prepare roll base material 5 and cladding material 4:

[0034] The roll base material 5 and the covering material are prepared according to the conventional machining process. The processed roll base material 5, that is, the matrix, is a solid or hollow cylindrical base material, and the processed covering material 4 is a height higher than the roll base. A round tube with a uniform wall thickness of 5 material. The material of the clad material 4 is the same as that of the welding wire used in the conventional continuous casting roll surfacing process. The roughness Ra of the outer surface of the roller base material 5 and the inner surface of the covering material 4 are both less than 6.3 μm. The inner diameter of the covering material 4 is larger than the outer diameter of the roll base m...

Abstract

The invention discloses a technology for explosively welding, processing and manufacturing continuous caster roller exploding. The technology includes the following steps: roller base material and clad material are prepared; roller base material and clad material are placed: the roller base material and the clad material coaxially arranged thereon are vertically fixed on a horizontal pedestal, and a cone piston is coaxially placed on the top of the roller base material; the external surface of the clad material is coated with a buffer protective layer; a cylindrical dynamite basket is inversely buckled on the pedestal and the cone piston and the clad material are both buckled in the dynamite basket, and clearance exists between coaxially arranged dynamite basket and clad material; main dynamite and ignition dynamite are distributed; explosively welding and consequential treatment are carried out. The invention with high production efficiency, low cost, energy saving, environmental protection and high product quality can effectively overcome the defects in the prior continuous cast roller production such as complicated overlaying welding procedures (preheating, bottom layer treatment and stratified overlaying welding), low production efficiency, high energy consumption, high cost, large labor intensity, environmental pollution and poor quality guarantee.

Description

technical field [0001] The invention relates to the technical field of continuous casting roll processing and manufacturing, in particular to an explosive welding processing and manufacturing process of continuous casting rolls. Background technique [0002] The continuous casting roll is the main part of the continuous casting machine in the steel plant to support and guide the billet. Because it has been working in the harsh environment of high temperature, water and humidity for a long time, the method of surfacing stainless steel on the surface of the roll is usually used to ensure its Long enough service life. For a long time, the surfacing welding of continuous casting rollers has been carried out on a special surfacing welding machine with stainless steel welding wire. There are many shortcomings in the processing process, which are explained from the following aspects: 1. In terms of production efficiency: the production efficiency of the original surfacing welding p...
