  一、变形热处理

  1、 Deformation heat treatment

  高温变形处理螺旋钢管的弯曲强度比和弹性极限。渐进式螺旋钢管的感应力学性能、疲劳性能和应力松弛性能。通过降低钢的增韧温度和脆性来降低钢的回火脆性。

  The bending strength ratio and elastic limit of high temperature deformed spiral steel tube. The induction mechanical property, fatigue property and stress relaxation property of progressive spiral steel tube. The tempering brittleness of steel can be reduced by reducing its toughening temperature and brittleness.

  螺旋钢管在高温变形处理中的作用是明显的。具体工艺流程如下:加热温度920 - 950℃,热轧时形状变量为10%—30%,风冷时间10 - 30s,油淬;然后一般在400℃以上或高温下快速回火。

  The role of spiral steel tube in high temperature deformation treatment is obvious. The specific technological process is as follows: heating temperature 920-950 ℃, shape variable 10% - 30% during hot rolling, air cooling time 10-30s, oil quenching; then rapid tempering is generally carried out above 400 ℃ or at high temperature.

  铁素体的化学热处理

  Chemical heat treatment of ferrite

  在氮化、氮化渗碳等铁氧体条件下进行化学热处理,可明显提高螺旋钢管的表面硬度、耐磨性、耐腐蚀性、残余压应力和疲劳寿命。化学热处理温度一般在450 - 600℃范围内,经调质处理的螺旋钢管可与化学热处理和调质相结合。化学热处理温度与桩硬化螺旋钢管相同。

  The surface hardness, wear resistance, corrosion resistance, residual compressive stress and fatigue life of spiral steel tube can be significantly improved by chemical heat treatment under the conditions of nitriding, nitriding and carburizing. The temperature of chemical heat treatment is generally in the range of 450 - 600 ℃, and the spiral steel tube after quenching and tempering can be combined with chemical heat treatment and quenching and tempering. The temperature of chemical heat treatment is the same as that of pile hardening spiral steel pipe.

  随着螺旋钢管的应用越来越广泛,对螺旋钢管的技术和产品多样性也提出了越来越高的要求。

  With the application of spiral steel pipe more and more widely, the technical and product diversity of spiral steel pipe is also put forward higher and higher requirements.
