广钢φ26无缝钢管分厂原有2座9×16m~2抽屉式室式退火炉,燃烧煤气或重油。热处理钢管品种为10～20号碳素钢,规格为φ10～70×1～6mm,生产能力3t/h。存在问题是产量低,能耗高、退火钢管质量差,机械性能不均匀。经退火后钢管弯曲度较大,而且钢管表面氧化铁皮厚薄不均匀,增加了矫直和酸洗工作量,劳动强度大。根 Guanghua φ26 seamless steel pipe factory original 2 9 × 16m ~ 2 drawer-type annealing furnace, burning gas or heavy oil. Heat treatment of steel varieties for the 10 to 20 carbon steel, specifications for φ10 ~ 70 × 1 ~ 6mm, the production capacity of 3t / h. The problem is the low output, high energy consumption, poor quality annealed steel, mechanical properties are not uniform. After annealing the steel pipe bending greater, and the uneven thickness of the steel surface oxide scale, an increase of straightening and pickling workload, labor-intensive. root
