摘要： A quenching apparatus that can enhance hardenability is provided. A circulation apparatus (50) in the quenching apparatus recovers cooling fluid after the cooling fluid is used for quenching, and supplies the cooling fluid to a defoaming bath (431). A laminar flow weir (433) of a defoaming apparatus (4) partitions the defoaming bath (431) into a laminar flow bath (434) and a shallow bath (435). The laminar flow weir (433) is lower than a side wall of the laminar flow bath (434). Cooling fluid from the circulation apparatus (50) is supplied to the laminar flow bath (434), and the cooling fluid is poured into the shallow bath (435) from the laminar flow bath (434) along the laminar flow weir (433). A filter (432) is a plate shape or a sheet shape and has a mesh structure, and covers an opening in a bottom portion of the shallow bath (435). The liquid level height in the shallow bath (435) is less than the height of the laminar flow weir (433). A supply bath (441) accumulates cooling fluid that passes through the filter (432), and supplies the cooling fluid to a cooling apparatus that sprays the cooling fluid onto a metallic material.

摘要： A quench system includes an enclosure defining a quench chamber sized to receive hot castings, and bulk air fans in fluid communication with the quench chamber and configured to establish a bulk flow of cooling air that surrounds and extracts heat from the hot castings at a first cooling rate. The quench system also includes a pressurized cooling system in fluid communication with a plurality of nozzles within the quench chamber and configured to spray a plurality of a directed flows of cooling fluid onto the hot castings to extract heat at a second cooling rate. The quench system further includes a programmable controller configured to sequentially activate the bulk air fans to cool the casting at the first cooling rate for a first predetermined period of time, and then activate the pressurized cooling system to cool the casting at the second cooling rate for a second predetermined period of time.

摘要： [Object] To provide a method for cooling a steel strip in a galvannealing furnace. The method performs mist cooling on a steel strip in a cooling zone of a galvannealing furnace and can achieve both productivity and quality. [Solution] The cooling method includes: by an adjusted cooling installation provided at an upstream side in a sheet-passing direction of the cooling installation, jetting mist to the steel strip passing through the cooling installation in a manner that an amount of mist jetted to the steel strip passing through the cooling installation is smaller in an edge portion in a width direction of the steel strip than in a center portion; by a mist suction installation provided at least at a downstream side in the sheet-passing direction of the cooling installation, sucking at least part of mist jetted to the steel strip; and cooling the steel strip at a sheet-passing speed such that, during a period between start and end of cooling of the steel strip, a temperature of the steel strip is within a film boiling temperature range and a temperature of the edge portion in the width direction of the steel strip is equal to or higher than a temperature of the center portion in at least a range of 2/3 or more from the upstream side in the sheet-passing direction of a total cooling length of the cooling installation.

摘要： [Problem to Be Solved]
To provide a novel briquetting roll having excellent performance such as providing both abrasion resistance and spalling resistance, which can also be manufactured at low cost and in a short period of time, and a method for manufacturing the same.
[Means for Solving the Problem]
A briquetting roll 1 integrally has an inner layer material 4 and an outer layer material 5, which comprise mutually different materials and are in contact with each other at the respective exterior and interior thereof, and has pockets 6 formed at the outer circumference of the outer layer material 5. A chromium-molybdenum forged steel material is used for the inner layer material 4 and a high-carbon high-speed steel material is used for the outer layer material 5. The outer layer material 5 may be formed on the outside of the inner layer material 4 by a continuous pouring process.摘要翻译： [要解决的问题]提供一种新型压块辊及其制造方法，该压块辊具有优异的性能，例如同时提供耐磨性和抗剥落性，其还可以以低成本和短时间制造。 解决问题的手段压块辊1一体地具有内层材料4和外层材料5，所述内层材料4和外层材料5包括彼此不同的材料并且在其各自的外部和内部彼此接触，并且具有形成的凹穴6 在外层材料5的外周。内层材料4使用铬 - 钼锻钢材料，外层材料5使用高碳高速钢材料。外层材料5 可以通过连续浇注工艺形成在内层材料4的外侧。
