Title: Method for controlling widthwise shape of hot rolling steel plate
Inventor: JANG JEONG HO
IPC: B21B37/00
Filed: 1998-12-09
Abstract: PURPOSE: A method for controlling a widthwise shape of a hot rolling steel plate is provided to obtain a good widthwise shape of the hot rolling steel plate by controlling a roll bending force and preventing a profile defect caused by the excessive setup of a fair cross and a work roll bender. CONSTITUTION: A target plate profile is set up and is rolled under the initial bending force. This time of the plate profile is measured so that the measured plate profile is indicated as an approximate function. The coefficient of the approximate function is obtained by the minimum involution. Next, thickness to plural plate widthwise points is obtained by putting the coefficient in the approximate function, and an average profile is obtained. After, a gap between the target plate profile and the average is obtained, a calibration bending force is obtained by using the gap. Accordingly, the initial bending force is calibrated as much as the calibration bending force.

Abstract: PURPOSE: A polyolefinic composition is provided, that is improved in an anti-tracking property and can be used for a high voltage insulating cable by maintaining consistently a tensile strength, the coefficient of expansion, and a volume intrinsic resistance. CONSTITUTION: The polyolefinic composition comprises 100 pts.wt. of a base polymer being either an alone of the polyolefinic elastomer or a blend of polyolefinic thermoplastic resin and polyolefinic elastomer; 10 to 200 pts.wt. of metal hydroxide as a tracking filler; 1 to 20 pts.wt. of metal oxide; 1 to 20 pts.wt. of a silane coupling agent; and 0.2 to 5 pts.wt. of an antioxidant. When the polyolefinic composition accompanies a crosslinking reaction including a chemical and irradiation crosslinking, the composition contains 1 to 3 pts.wt. of peroxide in the chemical crosslinking and 0.5 to 3 pts.wt. of an irradiation crosslinkage coagent in the irradiation crosslinking.
