Abstract
The utility model relates to a crystallization roller distributed with axial cooling water holes in a roller sleeve wall. The crystallization roller is characterized in that an axial hole type cooling water circulation loop system is arranged in the crystallization roller; the cooling water circulation loop system is formed in a way that one end surface in a mandrel at a swivel joint side is provided with two horizontal water outlet passages, and each horizontal water outlet passage is communicated and connected with a water inlet pipe of a swivel joint; the other end surface of the mandrel is internally provided with two vertical water inlet passages, and each vertical water inlet passage is communicated and connected with a water inlet pipe of the swivel joint; and along the axial direction of a roller sleeve, a plurality of long cylindrical axial cooling water holes are uniformly distributed in the roller sleeve wall, one end of each axial cooling water hole is communicated and connected with the corresponding water inlet passage, and the other end of each axial cooling water hole is communicated and connected with the corresponding water outlet passage. The crystallization roller not only has reasonable design, a compact structure, better thermal conductivity and strong heat exchange capability, and is easy for processing and assembly, but also has the advantages of being good in sealing performance, very convenient for operation and use, and the like.
Description
Technical field
The utility model belongs to the bimetallic continuous casting equipment, is distributed with the crystallization roller of axial cooling water hole in particularly a kind of roller shell wall.
Background technology
At present, the double roller continuous casting in the bimetallic continuous casting equipment with roll-type crystallization roller by roller shell and mandrel, sealing plug screw, hold out against ring, O-ring seals and screw and swivel joint is formed, its roller shell adopts copper or mild steel to make; Its roller shell interference is connected forms the crystallization roller on the mandrel cylindrical, the water hole end face that crystallization roller two ends are arranged is tightened with the sealing plug screw and is sealed, sealing between roller shell and the mandrel realizes that by the screw in compression O-ring seals that holds out against ring mandrel one end is a driving end, and the other end is equipped with swivel joint; In sealed at both ends crystallization roller, be provided with the closed circuit system of input and output cooling water, the closed circuit system of its cooling water be have vertically in the roller core Surface Machining, the cooling water groove of annular and screw type, with have tank in these corresponding crystallizers in groove position, import on this tank and outlet are communicated with the inlet tube of swivel joint and outlet respectively and join, thereby are implemented in the closed circuit of formation input and output cooling water in the crystallization roller.But the shortcoming and defect part of the closed circuit of above-mentioned cooling water is: the heat-exchange capacity when not only cooling off is not enough, makes slab thickness restricted, and roller core surface mechanical processing difficulty is bigger, assembling difficulty, poor sealing.
Summary of the invention
The utility model is intended to the shortcoming and defect part that exists in above-mentioned technology, and provide not only reasonable in design, compact conformation, both thermal conductivity was better, heat-exchange capacity is convenient to processing, assembling by force again, and has good airproof performance and manipulate the crystallization roller that is distributed with axial cooling water hole in a kind of very easily roller shell wall.
The purpose of this utility model is to adopt following technical scheme to realize: the crystallization roller that is distributed with axial cooling water hole in the described roller shell wall, comprise by mandrel, roller shell and form sealed at both ends crystallization roller and swivel joint, it is characterized in that: forming the cooling water circulation loop system that is provided with axial cellular type in the sealed at both ends crystallization roller by mandrel, roller shell; The cooling water circulation loop system of described axial cellular type is the water outlet that symmetry has two levels in the end face in the mandrel of swivel joint side, and the water outlet of each level is communicated with the outlet pipe of swivel joint and joins; Be arranged with two vertical inlet channels in the other end of described mandrel, each vertical inlet channel is communicated with the water inlet pipe of swivel joint and joins; Axial direction along roller shell, several elongated cylindrical that in the roller shell wall, evenly distribute, axial cooling water hole, one end of described each axial cooling water hole is communicated with corresponding inlet channel and joins, and the other end of each axial cooling water hole is communicated with corresponding water outlet and joins.
By the utility model on the axial direction of roller shell, evenly arrange several elongated cylindrical, axial cooling water hole, the tank of opening by correspondence position on this axial cooling water hole and the mandrel forms the closed circuit of input and output cooling water.Just improve the cooling velocity of crystallization roller in bath widely, just can increase the dimensions of the slab thickness of continuous casting.
The comprehensive above technical scheme of being taked realizes the purpose of this utility model.
Compared with prior art, characteristics of the present utility model are:
Consider in the composition metal casting process that 1, its pressure rolling power is less, to characteristics such as the case hardness of roller shell is less demanding and conceived the utility model.Its crystallization roller shell thermal conductivity is better, and heat-exchange capacity is strong, and the fatigue behaviour of heat-resisting alternate stress is remarkable to the molten steel crystallization effect in the bath, produces than the thick stock shell on the roller shell surface.Thereby cast out certain thickness compound strand.
2, owing in the roller shell wall, be the uniform axial cooling water hole in center on axially apart from excircle certain size place at it, isometrical water hole is opened towards the tank direction on the mandrel in each cooling water hole two ends, form the closed circuit of input and output cooling water, the two ends in long water hole seal with the sealing plug screw.
Therefore, the utility model is not only reasonable in design, compact conformation, and both thermal conductivity was better, and heat-exchange capacity is convenient to processing, assembling by force again, and has good airproof performance and manipulate advantages such as very convenient.
