Abstract

The utility model provides a mould for up-draw continuous casting copper rows which uses the up-draw method to continuously cast and produce copper rows. The utility model is characterized in that the cross section of the inner cavity of a graphite mould is corresponding to the cross section of a machined copper row, and the containing surface of the outer wall of the cross section of the machined copper row is similar to the cross section of the inner cavity. The inner cavity of a used cooling sleeve is provided with a pressure equalizing groove connected a water inlet pipe, and a water dividing plate is arranged on the lower part of the pressure equalizing groove.

Description

Continuous up-casting copper bar crystallizer

The utility model relates to a kind of continuous casting equipment parts, in particular for producing the continuous up-casting copper bar crystallizer of copper bar.

Be used at present to produce copper bar on draw the continuous casting crystallizer, the profile of its graphite mo(u)ld is cylindrical, therefore, exist the strand heat to be difficult for all around to transmitting, radiating condition is poor, and the appearance profile of crystallizer is also big, causes the waste of graphite material to improve cost again, and loads and unloads in use and problem such as difficulty.

The purpose of this utility model is exactly at the existing in prior technology problem, and a kind of graphite mo(u)ld profile and the cast copper row's of institute appearance similar is provided, and radiating condition is good, the continuous up-casting copper bar that cost the is low technical scheme of crystallizer.

This programme adopts following technical measures to realize.Mainly by graphite mo(u)ld 1 and its middle and upper part surround have water inlet pipe 8, continuous up-casting copper bar crystallizer that the coolant jacket 3 of outlet pipe 7 and protective sleeve 2 are formed, this programme characteristics are, the cross-sectional area of described graphite mo(u)ld 1 inner chamber is corresponding with the cross-sectional area of processing copper bar, and the outer wall female surface of its cross section is similar to the inner chamber cross section; The inner chamber position of described coolant jacket 3 is processed with balancing slit 4 with the top of graphite mo(u)ld 1 and is connected with water inlet pipe 8, and there is the dividing plate 5 of opening at the middle part in balancing slit 4, is connected with branch water plate 6 in the bottom of balancing slit 4.

This programme is because the graphite mo(u)ld profile that adopts is similar to its strand, thus strand to around to transmit heat even, good heat dissipation effect, and volume is little, thus reduced cost, in use not only be convenient to dismounting, also reduced the lost of furnace heat simultaneously.The water inlet pipe of coolant jacket directly is connected with the interior balancing slit of cover, makes the cooling water flow velocity even, and the extended flow process of cooling water of branch water plate is arranged again, and the utilization that has further improved cooling water has also strengthened cooling effect.This shows, the utility model compared with prior art, its effect is conspicuous.

Description of drawings:

Fig. 1 is the cross-sectional schematic of the utility model embodiment;

Fig. 2 is that the A-A of Fig. 1 is to cross-sectional schematic.

Below by a specific embodiment, and, technical characterictic of the present utility model is described in further detail in conjunction with its accompanying drawing.Continuous up-casting copper bar crystallizer is that the cross-sectional area of an inner chamber and the corresponding graphite mo(u)ld 1 of cross-sectional area of the copper bar of processing are arranged in its underpart, and the outer wall female surface of this graphite mo(u)ld 1 cross section is similar to the inner chamber cross section.Be surrounded by a coolant jacket 3 that has water inlet pipe 8 and outlet pipe 7 in the middle and upper part of graphite mo(u)ld 1, being processed with balancing slit 4 in the inner chamber position of coolant jacket 3 with the top of graphite mo(u)ld 1 is connected with water inlet pipe 8, there is the dividing plate 5 of opening at the middle part in balancing slit 4, is connected with branch water plate 6 in the bottom of balancing slit 4.In the outer wall bottom of coolant jacket 3, also be surrounded by the protective sleeve made from graphite material 2 in addition.

Claims

1. the continuous up-casting copper bar mainly is made up of coolant jacket [3] and protective sleeve [2] that graphite mo(u)ld [1] and its middle and upper part surround have water inlet pipe [8], outlet pipe [7] with crystallizer, of the present utility model being characterised in that, the cross-sectional area of described graphite mo(u)ld [1] inner chamber is corresponding with the cross-sectional area of processing copper bar, and the outer wall female surface of cross section is similar to the inner chamber cross section; The inner chamber position of described coolant jacket [3] is processed with balancing slit [4] with the top of graphite mo(u)ld [1] and is connected with water inlet pipe [8], and there is the dividing plate [5] of opening at the middle part in balancing slit [4], is connected with branch water plate [6] in the bottom of balancing slit 4.
