Four-high rolling mill is used for tempering. Worthington Makes Technology and Know-how Best in Class Keeping up with the latest in upgrades and maintenance makes our equipment operate at the highest level. High-strength cold-rolled steel sheet, and method for producing high-strength cold-rolled steel sheet. The bath is filled with an electrolytic solution. Alloying hot dip galvanized steel sheet for superdrawing excellent in resistance to secondary working brittleness and its production. This cooling method is shifted by connexion transition boiling initiation temperature in using hot water as cooling water in the low temperature side, the longer the film boiling duration This ensures it is intended to'll realize stable cooling.
Hot Rolled Steel Strip Coils
The Fe concentration in the plating layer was found by X-ray diffraction. Cold-rolled steel sheet and galvanized steel sheet, which are excellent in formability, panel shapeability, and dent-resistance, and method of manufacturing the same. Method for temperature-controlling and rolling ribbon steel for chain manufacture. It was cooled hot rolled strip according to the method of Patent Document 5. Hot Rolled Steel Strips.
Hot Rolled Steel Strips On ANS Steel Co.
In addition, no consideration is given to the effect of accumulated water on the steel strip, the occurrence of temperature deviation can not be avoided. Therefore, it is added in an amount of 0. Throughout Ran'nau preparative table, the strip upper surface side lamina first cooling, the strip lower surface is a spray cooling, the subsequent run-out table 2 1, 1 a water density of the cooling water 0 0 0 LZm Online determination method of continuous annealing line tension roller set roll surface roughness falling. Accordingly, it is desirable to appropriately determine the flow rate of cooling water and a pump to be used, taking into consideration the thickness of the steel sheet, the cooling rate, the feeding speed of the steel sheet, the length of the run-out table and so on.
For example, there is a preferable method of outwardly discharging water vapor generated by installing a ventilating system or forming a water vapor curtain using a chamber enclosing the run-out table, and a fan. Building low yield ratio hot-dip galvanized cold rolled steel sheet having improved refractory property. Production of bake hardenable galvanized steel sheet for ultradeep drawing having extremely outstanding secondary processability. However, according to the present invention, stripping of scales is carried out after a hot coil with a high temperature is quenched and then depressed at a thickness reduction rate of 0.
