Abstract
The utility model relates to metallurgy continuous casting equipment, particularly a continuous casting crystallizer which has the purposes that cooling water in a water seam completely takes part in cooling, and laminar flow is not generated. The utility model Is composed of an outer housing (1), an internal water jacket (2), a copper pipe (3) and a foot roller (4), wherein the water seam is formed between the internal water jacket and the copper pipe, and the surface of the wall of the water seam is rough and rugged; thus, the utility model improves the flow state of the water in the water seam and enhances the turbulence effect of water flow, the cooling water in the water seam can completely take part in cooling, cooling effect is raised, the service life of the crystallizer is extended, and the pulling rate of a continuous casting bloom can be correspondingly raised. Under the same cooling requirement, the differential pressure of a water inlet and a water outlet can be relatively reduced, the quality of the cooling water can be relatively reduced, and the occurrence of crystallizer accidents and running cost are reduced. The utility model has the advantages of reasonable structure, high cooling efficiency, reduction to the occurrence of crystallizer accidents and running cost, etc.
Description
Affiliated technical field: the utility model relates to a kind of metallurgical continuous casting equipment, particularly continuous cast mold.
Background technology: at present, widely used in the production of metallurgical industry continuous casting is tube type mold, generally by shell, inner water sleeve, copper pipe and sufficient roller are formed, copper pipe is fixing in the enclosure, the foot roller is arranged on enclosure, be provided with inner water sleeve in the enclosure, surround copper pipe, form gap (water seam) between inner water sleeve and the copper pipe, generally between 4-6mm, in this gap, there is the cooling water of certain flow rate that copper pipe is cooled off, owing to need in time the heat on the copper pipe to be taken away, the flow velocity of cooling water generally reaches 6-10m/s, the subject matter that the crystallizer of this class formation exists is: 1. the cooling effect of water performance is insufficient, when flowing through in the water seam of water between inner water sleeve and copper pipe, have only the part water particle really to participate in heat exchange with the copper pipe wall, most water particles are just after stitching by water, mix with the water particle that obtains heat in the zone beyond the water seam, participated in heat exchange indirectly, the cooling effectiveness of cooling water is just very low like this, thereby limited the raising of continuous casting casting speed, the reason that this problem occurs is that the inner water sleeve or the copper pipe surface of formation water seam is smooth, the water slotted wall smooth surface of formation, and the out-of-date formation laminar flow of cooling water flow causes.2. owing to above reason, keep certain cooling effect, just must increase the pressure reduction of water inlet and delivery port, keep cooling, be easy to cause crystallizer to leak, have an accident with higher flow velocity.3. owing on the copper pipe outside wall surface, there is the laminar sublayer that speed is extremely low, temperature is very high, cause the very easily fouling of copper pipe outer wall, worsen heat transfer condition, cause the bleed-out accident to take place, therefore need carry out strictness control to quality of cooling water, to reduce the fouling of copper pipe wall, still increased the operating cost of cooling water.
The utility model content: the utility model purpose provides a kind of continuous cast mold, makes when flowing through in the water seam of cooling water between inner water sleeve and copper pipe, and cooling water all participates in cooling in the water seam, do not produce laminar flow, solves the problems referred to above that background technology exists.
The technical solution of the utility model is: the water slotted wall rough surface that forms between the inner water sleeve of crystallizer and the copper pipe, and rough and uneven in surface.
Can on inner water sleeve or copper pipe wall some ribs be set, rib is arbitrarily arranged, can connect whole water seam.
Can also on inner water sleeve or copper pipe wall some protrusions be set, the shape of protrusion is arbitrarily, can be circular, have corner angle etc. shape.Protrusion can be arranged arbitrarily, also can regularly arrange.
Adopt the utility model, because the water slotted wall rough surface between inner water sleeve and the copper pipe, rough and uneven in surface, improved the flow regime of water in the water seam, strengthened the turbulence effect of current, make cooling water in water seam, all participate in cooling, improve cooling effect and crystallizer service life, the corresponding pulling rate that can improve continuous casting billet.Under the condition that equal cooling requires, can reduce the pressure reduction of water inlet and delivery port relatively, reduce relatively, reduce crystallizer accident and operating cost the quality of cooling water requirement.
The utlity model has rational in infrastructure, cooling effectiveness is high, reduce characteristics such as crystallizer accident and operating cost.
