Abstract
A prestressed crystallizer composite copper sleeve is provided, which is characterized in that: the utility model is provided with an inner layer and an outer layer sleeve jointed with each other and with junction surfaces embedded into a whole. The inner layer adopts the copper alloy while the outer layer adopts the chrome copper. The utility model can also adopt three layers, namely a middle layer embedded between the inner layer and the outer layer. The utility model has the advantages that the crystallizer copper sleeve becomes a composite whole with multi levels and different organizational structures so as to thoroughly change the internal organization of the crystallizer copper sleeve and form an alternative form of organization. The internal sleeve adopts copper alloy with high performance to upgrade the mechanical performances of the copper sleeve such as tension resistance and ensure the high temperature mechanical performance requirement of copper sleeve, thereby can thoroughly avoid the occurrence of boiling accident of the copper sleeve (perforation) with good safety performance and low production cost. The crystallizer has good conductivity performance of heat and electricity and the production efficiency of steel is improved. Due to that the internal sleeve adopts the whole prestress lining technology, the problem of copper sleeve failure (damage) caused by uneven partial adhesive force does not exist.
Description
Technical field
The utility model relates to a kind of compound copper sheathing of prestressing force crystallizer that is used for continuous casting installation for casting.
Background technology
(name is called No. 98119193 patents of Chinese patent: the crystallizer of continuous casting installation for casting) be the crystallizer that is used for continuous casting installation for casting, this crystallizer is to adopt the mode of coating to be provided with a kind of coating of forming than the material of Crystallizer tube material thermal conductivity difference in the crystallizer outside, coating mainly adopts metals such as chromium plating, nickel to improve the wear resistance at elevated temperature of copper sheathing, improves copper sheathing service life thereby reach.But can't improve the mechanical strength of copper sheathing, can not thoroughly solve crystallizer boiling accident.Owing to adopt coating technology influenced by the power that conforms to of coating, the easy partial failure of coating causes copper sheathing to descend service life, and metal material thermal conductivities such as chromium, nickel are lower, and directly energy is given birth in the trace heat conduction that rings copper sheathing.
Summary of the invention
The purpose of this utility model just provides a kind of change crystallizer copper sleeve interior tissue, form staggered complementary tissue morphology, interior cover adopts high-performance copper alloy material, the mechanical performances such as an anti-resistance to compression of copper sheathing have been improved, guaranteed the requirement of the living energy of copper sheathing high-temperature machinery simultaneously, can thoroughly solve copper sheathing (perforation) boiling accident and take place.
Solution of the present utility model is such: have two mutual sockets at least, inlay internal layer and the skin that forms one at its faying face.Described internal layer is to adopt different materials to inlay to form with skin.Owing to adopt the prestressing force compacting, inside and outside layer is embedded as a whole, thoroughly changed crystallizer copper sleeve metal structure, formed the tissue morphology of staggered complementation.
The utility model also can adopt three layers, is inlaid with the intermediate layer between internal layer and skin, adopts three layers to inlay and form, and it is inequality having two layers of material at least.。
The utility model has the advantages that by prestressing force edge layer, crystallizer copper sleeve is formed at many levels, the composite monolithic of different tissues structure, thoroughly changed the metal inside tissue of crystallizer copper sleeve, formed the tissue morphology of staggered complementation, interior cover adopts high-performance copper alloy material, the mechanical performances such as an anti-resistance to compression of copper sheathing have been improved, guaranteed the requirement of copper sheathing high-temperature mechanical property simultaneously, can thoroughly solve copper sheathing (perforation) boiling accident and take place, safety is given birth to can be good, and production cost is low, the electrical and thermal conductivity performance of crystallizer is good, and steel production efficiency is improved; Because interior cover adopts integrated prestress edge cover technology, does not exist the part to conform to the problem that the power inequality causes copper sheathing inefficacy (damage).
