The utility model discloses a contact type lithium battery roll core thickness measuring device, which comprises an upper pressing plate and a lower pressing plate, the upper pressing plate is fixed at the lower part of a top plate, the front surface of the top plate is provided with a thickness measuring probe, the thickness measuring probe is provided with an elastic component, small-stroke elastic displacement of the probe end can be realized, and the contact point of the thickness measuring probe is on the surface of the lower pressing plate; the top of the top plate is connected with a cylinder pushing mechanism, and the cylinder pushing mechanism drives the top plate and the upper pressing plate to descend synchronously, so that the distance between the upper pressing plate and the lower pressing plate is reduced, and a roll core placed on the lower pressing plate is pressed; according to the utility model, the thickness of the pole piece in the roll core can be measured in a compact state through a contact type pressing measurement mode, and the measured thickness of the roll core is more accurate.

This invention relates to a medium-high fluorine, low-alumina slag system for electroslag remelting S-06 stainless steel, belonging to the field of electroslag special metallurgical technology. It addresses the problems of high fluorine content, significant pollution, and poor uniformity of steel ingots produced by existing electroslag remelting slag systems. The mass percentage of each component in the medium-high fluorine, low-alumina slag system of this invention is as follows: CaF2: 56.4%~57.3%, Al2O3: 11.5%~14.9%, CaO: 19.7%~20.2%, MgO: 8.0%~10.0%, SiO2: 0.9%~1.1%, C: 0.04%~0.06%, with the remainder being impurities. The slag system of this invention exhibits good metallurgical effects; when using this slag system for electroslag remelting S-06 stainless steel, the resulting steel ingots show uniform elemental distribution and a uniform slag coating.

This invention relates to a low-fluorine, high-calcium desulfurization slag system for electroslag remelting S-06 stainless steel and its application method, belonging to the field of electroslag special metallurgical technology. It addresses the problems of high fluorine content and pollution in existing electroslag smelting slag systems, resulting in poor uniformity of the prepared steel ingots and uneven, thick slag skin. The mass percentage of each component in the low-fluorine, high-calcium desulfurization slag system of this invention is as follows: CaF2: 38.3%~42.1%, Al2O3: 23.2%~24.8%, CaO: 30.9%~32.8%, MgO: 1.0%~5.0%, SiO2: 0.8%~1.0%, C: 0.07%~0.1%, with the remainder being impurities. The slag system of this invention exhibits good metallurgical effects; when using this slag system for electroslag remelting S-06 stainless steel, the resulting steel ingots have a uniform elemental distribution and a uniform slag skin.
