Description
Technical field
The present invention relates to metallurgical continuous casting apparatus field, is more particularly to a kind of metal continuous cast liquid cooled crystalliser.
Background technology
Crystallizer of the prior art, a kind of liquid cooled crystalliser of metal continuous cast as disclosed in CN03127762.4, bag
The crystallizer plate (1) of copper or copper alloy is included, it is connected by fixing bolt (14) with pinboard or water tank.The feature of this crystallizer
It is, fixing bolt (14) is fixed on from the platform (7) of crystallizer plate (1) coolant side (6) island-projection, platform at least portion
Divide and stretch into the cooling agent gap that crystallizer plate (1) is formed between pinboard or water tank and flowed with a kind of with cooling agent
The adaptable streamlined moulding in direction (S).Its advantage is：Crystallizer plate is by platform supports in adjacent pinboard or adjacent
On water tank.What need not be added in this case is used to form the spacing element in cooling agent gap, because platform determines to finish
Spacing between brilliant device plate and pinboard or water tank and thus also determine the width in cooling agent gap.So in design principle not
The other grooves or groove of guiding cooling agent must be set in pinboard or crystallizer plate.That is, pinboard and crystallizer
Plate may be designed to flat in addition to platform in coolant side, thus fundamentally eliminate to manufacture additional coolant channel or groove
Expense in terms of required process technology.Of course, it is possible to not only can be in pinboard but also can be in crystallizer plate extremely by selection
Few part sets some coolant channels or groove.It is disadvantageous in that：1）Hundreds of boss of milling, difficult processing on copper coin dorsal part
Degree and cost well imagine, also needs to platform being processed into streamlined structure when important, difficulty of processing very, and by whole copper
Plate carries out milling, mills away many copper materials and wastes substantial amounts of raw material, copper product is expensive to process and prepare copper plate of crystallizer cost
It is high.2）Copper plate of crystallizer reached after service life, it is necessary to which the copper plate of crystallizer that more renews is, it is necessary to by hundreds of bolts from boss
It is upper to take out, it is necessary to new copper coin is processed into back again has the copper coin of some boss, change each time be required to process it is convex
Platform, processing cost are high.3）Although setting boss to increase contact depth of the boss internal thread with bolt on copper coin,
Larger screwed hole is set in boss, boss the week side of boss formed thin-walled cause to connect it is insecure, to increase bolt and screwed hole
Firmness, the diameter of thread of boss can only be reduced, but the diameter of bolt reduces the firmness for not reaching needs equally, can only be in copper
More boss are set on plate, set more boss to reduce the contact area of copper coin and water, cooling performance declines.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of difficulty of processing is low, production cost is low, recycles utilization rate
High metal continuous cast liquid cooled crystalliser, reduce be connected in copper or copper alloy crystallizer inner panel with support plate or water chamber plate it is insecure
Problem, and do not increase work plate thickness reliably bearing tension and thermic load is fixed on Cu crystallizer backboard.
The technical solution used in the present invention is：A kind of metal continuous cast liquid cooled crystalliser, including crystallizer plate and switching
Plate, the crystallizer plate are connected by bolt with pinboard, and the pinboard is provided with several boss.
Several through holes of boss are provided through on the pinboard.
The boss and pinboard integrative-structure.
The boss is provided with annular seal groove.
Gask-O-Seal is provided with the annular seal groove.
The pinboard dorsal part through hole is provided with the shoulder hole entered for nut.
The shoulder hole is provided with sealing-plug.
The crystallizer plate is provided with the screwed hole to match with bolt.
Hole is threaded on the copper coin of the present invention, is provided with thread bush in screwed hole, bolt is installed into copper coin through backboard
Thread bush in, make copper coin and backboard by bolt drawing together with；Boss on backboard supports copper coin, makes copper coin and backboard
Between form cooling gap；There is seal groove on the boss of backboard, can prevent cooling water from being seeped water to bolt position after sealing ring is installed,
Be advantageous to improve the security of equipment；The crystallizer cooling performance of this structure is more uniform, is advantageous to improve continuous casting billet quality；
Backboard can be long-term use of, has interchangeability.Copper coin is expendable part, can repeat to change.Because copper coin is thinner, light weight, take
Cost is lower.Relative to design of the boss on copper coin, this structure difficulty of processing is low, relative to prior art in crystallizer copper
Milling boss on plate, overall cost can reduce by 60%.
