Description

Water pot

Technical field

The utility model relates to a kind of continuous casting equipment, relates in particular to a kind of for the production of low melting point, low than the pot that waters of thermalloy cast.

Background technology

At present, generally include steel band, wheeled steel, circumference for the production of copper alloy, aluminium alloy electrician with its crystallizer of conticaster of pole stock, sheet material and be provided with the crystallizing wheel of annular groove, steel band successively after crystallizing wheel and a plurality of wheeled steel to crystallizing wheel.Steel band is guided, tightens and with crystallizing wheel, be adjacent to by a plurality of wheeled steels, seal the formation of crystallizing wheel groove outer rim by steel band and circumferentially by casting gate, extended to the die cavity of throwing outlet along crystallizing wheel, be forced to crystallisation by cooling in die cavity forms strand to molten metal afterwards from the casting gate injection by watering pot, and the strand of formation is pulled out from the throwing outlet.

The existing pot that waters comprises the liquid level chamber of depositing metal liquid and the pouring mouth that is used for casting of molten metal, and pouring mouth is arranged in the groove of crystallizing wheel casting port position, below existing pot shortcoming of watering is done following analysis:

One, the contact-making surface sealing of the existing pouring mouth that waters pot and crystallizing wheel is not tight, has the phenomenon of molten metal along pouring mouth and the leakage of crystallizing wheel groove contact-making surface, thereby causes molten metal to flow backwards along crystallizing wheel.

When two, steel band forms degree of lip-rounding die cavity after sealing crystallizing wheel groove outer rim due to recess width wider (approximately 1.5m), the steel band supporting with it is inevitable wider, during the broadband closed pockets because only only the outer rim on fluted both sides support steel band, steel band causes arc deformation under the effect of gravity, namely affected the shape of die cavity, make the plate surface of producing have radian, can not reach smooth requirement.And the existing pouring mouth that waters pot does not design steel band supporting construction yet, cause steel band because of gravity generation deformation, affect the base type of the die cavity that is formed by crystallizing wheel groove and steel band, thereby caused the plate surface of producing to have certain deformation, can not meet production requirement.

Three, water the general dregs that all have the generations such as casting thawing in metal liquid surface of the liquid level indoor storage of pot, with being with metal liquid pouring cast part dreggy can cause slag class defect, and the existing pot that waters does not also have a kind of effective deslagging device.

Four, existing pot liquid level of watering is non-constant, thereby cause when watering pot liquid level when higher, pouring mouth casting flow quantity is large, unit interval pours into a mould into crystallizing wheel die cavity interior plumbous liquid or other molten metals too much, cause the outflow along the fine gap trace at steel band and crystallizing wheel edge of plumbous liquid or other molten metals, cause stereotype moulding back edge that overlap (burr) is arranged.When liquid level was too low, molten metal did not connect, and air enters, and caused fracture, the defects such as bubble.

Five, existing metal liquid temperature of watering in pot is non-constant, thereby affects the crystallization effect of follow-up crystallizing wheel to stereotype., because the adjustment parameter of the casting wall temperature adjusting device of crystallizing wheel and cooling system has set in advance, only has the well crystallization of casting metal liquid that coordinates steady temperature.Why existing continuous stereotype casting machine can not cast wider stereotype, its main cause is exactly because prior art is controlled perfect not to the crystallization temperature of plumbous liquid or other molten metal, it is excessive because of the sheet material width when casting is than the wide plate material, in molten metal crystallisation by cooling process, the regional temperature crystallization effect that differs is bad, when wide from the stereotype that causes casting, milling train can not be completed.
