Description of the invention (1) According to item B before the first patent application park, the present invention relates to a chilling mold for continuous casting of steel. (Please read the notes on the back before filling this page.) In continuous casting of slab and small ingot formats, tubular chilled molds are used almost without exception. Where the cavity is limited by the chilled mold tube, the Cold mold tubes are made of copper or copper alloy tubes with a wall thickness of 8-25 mm, and are produced by "11 many expensive operating insects. 1 Adding .T to increase the hardness to give the necessary strength to the chilled mold tube. In addition to the cost of the material, especially the method of hardening and forming the material, the production cost is increased. The chilled mold tube creates a funnel in the mold cavity. And the chilling mold tube has one or more smooth walls on the outside. In most cases, the mold cavity has a covering μ formed by chromium and nickel on the m plating. In order to cool the tubular chilling mold, water is forced At a high speed of 6-1 4 m / S, it flows through the outer side of the copper pipe in the water gap. In order to uniformly cool the copper pipe, a certain width of the water gap is required. On one side, the water gap is determined by the external dimensions of the copper pipe, and on the other side However, the water jacket lh matches the outer jacket

Description of the invention (2) In order to avoid the increase of the cross section of the cast steel bar, it is known that chilling is performed on a mandrel that matches the size of the cavity. Explosive deformation of the mold tube. Other pressure processing methods to reshape the widened tube are also known. All these waddam molding methods, such as explosion recalibration or pressure recalibration, have a common disadvantage. That is, the outer cross section of the chilled mold tube is reduced. As a result of the reduction of the cross section, the water gap between the chilled mold tube and the water jacket is uncontrollably enlarged, which brings about the cooling of the chilled mold. The disadvantage of the present invention is to eliminate the defects in the prior art. In particular, the new design of the chilling mold structure of the tubular chilling mold can eliminate the production cost of the steel chilling mold and the ingot quenching service made of cold drawn tubes made of mountain copper or copper alloys. · The foot of the step has a significantly longer life. Through the calibration of the step, the cavity area can be restored to the required chill mold structure. According to the present invention, all of the above steps can be il l The application of the special chilling die described in item 1 of the patent application can use the chilling die according to the present invention to overcome the shortcomings of the prior art in the case of tubular chilling and to avoid the billet made of copper cold-drawn tubes.

Description of the invention (3) Casting parameters such as prayer temperature or loss of steel composition can also be adapted. .It is assumed in advance that the covering ® exhibits a considerable degree at the casting temperature (please read the precautions on the back before filling this page). Υ The consumer cooperation of the Intellectual Property Bureau of the Ministry of Economic Affairs is printed in the case of a tube chill mold. The chilled mold tube must have one side to ensure high heat absorption, and the other to ensure the required load stability. The usage of Jing Hao's program is regarded as a standard of negative stability. At least two factors affect the stability of chilled mold tubes. The stability of the chilled mold tube, 迕 'J) Surface 1 is determined by its ability to withstand high thermal loads during casting operations, that is, when the inner side is in contact with the metal melt while the outer side is intensely cooled. The stability of chilled mold tubes is also determined by their ability to withstand mechanical stress during casting operations. In order to make the chilled mold tube have sufficient size and stability, the K resistance and the density can withstand the leg force of the cooling water, especially when the pressure of the cooling water acts on the entire jacket of the chilled mold tube. Casting flat .. 丨.: There is no corresponding balanced M force on one side of the mold cavity, and the metal melt only generates balanced leg forces that increase as the distance from the prayer plane increases. Make every effort to build a copper pipe with a thermal load and mechanical load, depending on the casting format, and a copper tube with a suitable negative stability, usually 冇 8-2 5 ΙΉ m wall thickness. As the wall thickness increases, heat is absorbed. The property decreases, even in the case where the material exhibits high thermal conductivity. In the case of the chilling mold according to the invention of the wood, the wrong reason is that the square blood is the window cover M: the appropriate material is selected for the bottom, and the W-square iff is 蒗Select the appropriate material for the cover, the requirements for heat dissipation and the stability of the inner body forming the cavity > can be optimized independently of each other, for example, 'the covering substrate can be set so that the inner body provides High mechanical strength and the form that guarantees the stability of the inner body, ifli can choose to cover the thermal properties and thickness of the body.

'~~ Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs a 〇456 4 A7 I-: __ 一 Β7 V. Description of the invention (4) The heat dissipation of the inner body is optimized. The M layer made of a material with enhanced mechanical strength appears at the bottom. The thin mold wall thus enhances the heat absorption of the chilled mold. It is assumed in advance that the covering layer can be renewed. Through repeated repairs, the chilled mold can obtain a significantly longer service life. According to the present invention, aluminum or aluminum is proposed. Covering substrates made of alloys, such as alloy A1MgS 11, known as aluminum clump anvil, gold-containing Antic01.0da 1 W Ν 6 0 8 2. Aluminum or aluminum alloys exhibit a range of i 3 0-2 2 0 W / m K The thermal conductivity of the inner layer. Since the cover substrate is always located within a limited distance from the metal melt introduced into the mold cavity during the casting operation, the distance is determined by the thickness of the cover layer and the inner body is cooled, so it can be used in the casting operation. In the coating layer base 4 made of aluminum alloy, the aluminum or aluminum alloy is maintained at a particularly high temperature. In addition, the hardening mold M made of aluminum or aluminum alloy can be used in a relatively inexpensive manner. Such as extrusion to produce >> The cover layer can adapt to the special requirements in the continuous mirror manufacturing process. This requirement also includes the longitudinal change of the chill mold and the change of w due to the unsatisfactory level of steel made at least near the melting point. The upper part of the metal bath table is so good Choose a material with a high thermal conductivity as the cover layer, such as copper or copper alloy with a thermal conductivity of 200-4 00W / m K. In the lower part of the cavity, you can also think of a harder material such as nickel. In order to ensure that in the mirror-making operation, even under extreme conditions, the base cover layer is not overheated and exhibits a high level of strength and dimensional stability, the grain cover layer has a thickness of 0.5 to 5 mm. It is best to achieve a thickness of 1 to 4 mm. The covering layer can be plated or gold coated or thermal sprayed. For example, flame spraying or plasma spraying is less productive.

Invention Explanation (10). Other lubricating materials known in the prior art that can be added to the barrier layer are also included in the present invention. In the embodiment of FIGS. 1-3, only The vertical chilling mold is described, but the present invention is not limited to this type of chilling mold with a vertical cavity.

In this way, the probe can be placed in the cover: After the cover layer is applied, Ran creates a hole that is suitable for the measurement probe as the cover layer II. It is well known that placing probes in holes can only be controlled in a less precise way. If the probe is as described in "_:", embedding the cover layer in the production process of coating the cover layer can avoid this kind of inaccuracy, and this inaccuracy is caused by the inaccuracy of the probe for measurement. ... a variety of sources.
