摘要： PURPOSE:To obtain stably a bar stock and a wire rod of an alpha+beta type titanium alloy in the high velocity in the continuous hot rolling of titanium alloy by performing the intermediate winding on the way of a rolling-mil series, holding or cooling it and thereafter rolling successively it in a zone alpha+beta in the downstream. CONSTITUTION:A billet of alpha+beta type titanium alloy is heated at 850-950 deg.C and continuously rolled. In this case, an intermediate winder as a stock storing device is provided in the middle of a continuous rolling-mill series. The wound intermediate is held or cooled by providing a cooling device and a heat-up device to the winder and the temp. of the surface and the central part is soaked. Then the rolling is furthermore continued in a zone alpha+beta in the rolling-mill series of a rear stage. By this method, a small bar stock and wire rod of titanium alloy excellent in the structure can be stably manufactured in a high- velocity rolling line.

摘要： PURPOSE:To destroy effectively the cast structure over the whole sheet thickness and to improve ridging resistance, by casting the ferritic stainless steel contg. a specific amount of Cr and by hot-rolling the plate after holding in a specific temp. CONSTITUTION:An ingot of ferritic stainless steel contg. >=10% Cr is cast, which is held at 700 deg.C - Ac3 point for >=30min, without cooling to
摘要翻译：目的：通过铸造铁素体不锈钢，有效地破坏整个板材厚度的铸造结构，提高抗皱性能。特定量的Cr和通过在保持特定温度之后热轧板。构成：铁素体不锈钢锭 > = 10％Cr铸造，其保持在700℃-Ac3点> = 30min，而不冷却至<= 300℃。这种热处理加速了奥氏体相转变成铁素体相并进入碳化物。如果需要，将该锭重新加热，进行热轧，退火，并进行冷轧。以这种方式，能够提高铁素体系不锈钢板的耐波纹性。

摘要： PURPOSE: To manufacture the titled stainless steel sheet, by cooling ferritic stainless steel slab contg. specified ratios of Cr and Al, then holding it at a specified temp. to cause transformation of martensite phase to ferrite phase and carbide, and hot rolling said slab.
CONSTITUTION: Ferritic stainless steel slab contg. by weight, ≥10% Cr, ≥0.06%W≤0.3% Al is cooled, then held at ≥700°CW≤Ac
3 point for ≥30min to transform martensite phase to ferrite phase and carbide. Next, the slab is hot rolled, if necessary, said plate is annealed then cold rolled. By this way, cast structure is destroyed advantageously over whole sheet thickness, and ridging property is improved.

摘要： PURPOSE:Title lubricant capable of forming a tough lubricating film which reduces wear of rolls, prepared by dissolving or dispersing a metallic soap in a wax type or an oil and fat type lubricant which is solid or semisolid at normal temperature. CONSTITUTION:At most 25wt% of one or more of metallic soaps selected from metal salts of a higher fatty acid are dissolved or dispersed in a wax type or an oil and fat type lubricant which is solid or semisolid at normal temperature, such as shellac or beef tallow, to produce a hot rolling lubricant. This lubricant is molten by heating, divided into mists by air heated to at least 70 deg.C, and sprayed over a steel material to form a lubricating film.
