The conclusion was drawn by the synthesis of molecular sieve: after mixed soluble glass and aluminium sulfate with proper proportion under room temperature, it was stirred stormily to react. And then we mixed with potassium hydroxide solution after filtrating. At last, the molecular sieves of potassium type was synthesized after the mixture reacted in the oven or autoclave for 24 hours. The molecular sieve was remodeled more than twice with ammonium chloride solution that the concentration was 3mol/L and then remodeled twice with the saturated sodium chloride solution. Finally the molecular sieve was changed into the sodium type. It was named W zeolite.

通过对分子筛的合成得到:以泡花碱、硫酸铝为原料,以硅铝比按一定比例于室温下将二者混合,激烈搅拌,抽滤后与氢氧化钾溶液混合放于烘箱或高压釜中高温晶化24小时,晶化后的分子筛为钾型,先后用3mol/L氯化铵溶液和饱和食盐水各对其改型两次以上,最后改为钠型,可制得W型沸石分子筛。

Heating billet temperature cannot be detected in the hearth. Only by detecting temperatures of the stove side or hearth with estimation from mere experience could lead to great error on the measurement of billet temperature and affect the quality of post-processing accordingly; Overheating also exists in the heating process, and the quality of product is sway by overheating oxidation. Though infrared thermoscope is used to detect the temperature of billet when it is taken out of the stove, precision is still affected because of the oxide layer on the surface.

燃气与空气的配气量比例,一般通过人工调节,未实现按加热条件自动动态调节;无法在炉膛内检测被加热钢材的温度,只能通过检测炉壁或炉膛温度,再凭经验估计钢材温度,结果是钢板温度误差大,影响后续加工质量;钢材加热存在表面过烧现象,有时表面烧损、氧化严重,影响产品质量;尽管钢材出炉时,可用红外线测温仪来进行钢材表面温度检测,但因钢材表面存在氧化层,也影响钢材温度检测精度。
