摘要： A molded product which is molded with thermoplastic resin by a thermal deposition method. The method uses a substantially ring-shaped resistance heating element. A hole is provided for impressing the voltage by inserting the electrode from this hole and impressing the voltage to the resistance heating element. Thereafter the hole is blocked. The electric resistance heating body is disposed between the composition planes of the parts which are to form a body.

摘要： A compound roll for rollng composed of a shell made of high-chromium cast iron and a core made of cast or forged steel. The shell has a large residual compressive stress. The high-chromium cast iron shell has a composition by weight of 2.0-3.5% C, 0.5-1.5% Si, 0.4-1.5% Mn, 8-25% Cr, 0.5-3.0% Mo, 1.5% or less Ni and the balance being essentially Fe for hot rolling, and 2.5-3.5% C, 0.5-1.5% Si, 0.4-1.5% Mn, 0.5-3.0% Ni, 8-25% Cr, 1.0-5.0% Mo and the balance being essentially Fe for cold rolling. The shell's Shore hardness is 70 or more for hot rolling and 90 or more for cold rolling, and the core's tensile strength and elongation are 55 kg/mm.sup.2 or more and 1.0% or more, respectively. The residual compressive stress of the shell is 20 kg/mm.sup.2 or more and serves to prevent cracks from penetrating into the depths of the shell, thereby preventing spalling effectively. This compound roll can be manufactured by a shell casting method.
摘要翻译：一种由高铬铸铁制成的壳体和由铸造或锻造钢制成的铁心组成的轧制复合辊。壳体具有较大的残余压应力。高铬铸铁壳的重量比为2.0-3.5％C，0.5-1.5％Si，0.4-1.5％Mn，8-25％Cr，0.5-3.0％Mo，1.5％或更少的Ni，余量基本上为Fe的热轧，2.5-3.5％的C，0.5-1.5％的Si，0.4-1.5％的Mn，0.5-3.0％的Ni，8-25％的Cr，1.0-5.0％的Mo，余量基本上是Fe 用于冷轧。壳体的肖氏硬度为热轧时为70以上，冷轧为90度以上，芯部的拉伸强度和伸长率分别为55kg / mm 2以上且1.0％以上。壳体的残余压应力为20kg / mm2以上，用于防止裂纹渗透到壳体的深度，从而有效防止剥落。该复合辊可以通过壳铸造法制造。
