The invention discloses bake hardening type high-strength steel. The bake hardening type high-strength steel comprises, by mass percentage, 0.05 to 0.13% of C, 0.05 to 0.20% of Si, 0.50 to 1.50% of Mn, 0.02 to 0.06% of Al, larger than 0 and not larger than 0.0050% of N, and the balance iron and other inevitable impurities, and in addition, the condition that B-0.77*N is larger than or equal to 0.0005 and smaller than or equal to 0.0020% should be met. According to the bake hardening type high-strength steel, under the condition of not adding precious metals such as Mo, Cr, Ti and Nb, by controlling the mass percentage of carbon, manganese and boron, the technological processes and the technological parameters, the steel which is high in strength, low in cost, high in surface quality and of which the machining performance meets the requirements of automotive parts is manufactured.

The invention belongs to the technical field of galvanized steel sheet production methods, and relates to a finishing withdrawing-straightening tension control method for a deep-draw galvanized steel sheet for guaranteeing the steel sheet performance and the surface quality. According to the technical scheme, the tension set values before and after the finishing withdrawing-straightening are adjusted, and the matching relation between steel plates with different thicknesses and the tension before and after the finishing withdrawing-straightening is adopted, wherein the tension before finishing conforms to the formula: T(strip steel thickness)*(25-30)KN, and the tension after finishing and withdrawing-straightening conforms to the formula: T(strip steel thickness)*(27.5-33)KN. According to the finishing withdrawing-straightening tension control method, the surface quality of the deep-draw galvanized product can be guaranteed, the performance is not greatly affected, the requirement for machining and using performance of a user is met, and the performance aggravating effect brought by increasing the finishing rolling force to guarantee the surface of the deep-draw galvanized product is avoided. The performance judgment amending ratio of the deep-draw galvanized product is greatly reduced, the surface quality and the profit space of the deep-draw galvanized product are greatly improved, the competitiveness of enterprises is enhanced, and considerable economic benefits are brought to the enterprises.

The invention discloses a production method of glass fiber SMC yarn, which comprises the following steps: 1) preparation of an impregnating agent; 2) dosing; 3) melting in a kiln; 4) bushing; 5) coating with the impregnating agent; 6) drawing; 7) drying; 8) roving winding; 9) inspection and storage.
