The invention belongs to the technical field of high-temperature alloy smelting, and relates to a process for improving the surface quality of a first-class Ni-Fe-Cr-based high-temperature alloy consumable cast ingot and application. Comprising the following steps: firstly, performing vacuum induction melting on a high-temperature alloy to obtain a high-temperature alloy VIM electrode; then, the high-temperature alloy VIM electrode is subjected to protective atmosphere electroslag smelting, and a high-temperature alloy ESR electrode is obtained; and the high-temperature alloy ESR electrode is subjected to annealing treatment, finally, the high-temperature alloy ESR electrode is subjected to vacuum consumable smelting, and a high-quality high-temperature alloy ingot is obtained. According to the high-temperature alloy cast ingot produced through the method, forging cogging can be carried out after direct homogenization without scaling treatment, the production process is shorter, the delivery pressure is smaller, and the cost is lower.

The present invention relates to a sulfonic acid derivative of naphthalimide and a photo-acid generator and photoresist composition each containing the sulfonic acid derivative of naphthalimide, more specifically, to a sulfonic acid derivative of naphthalimide compound and a photo-acid generator and photoresist composition each containing the sulfonic acid derivative of naphthalimide compound, wherein the sulfonic acid derivative of naphthalimide compound has excellent absorbency to light of i-line (365 nm) wavelength, is very easy to prepare a polymerizable composition due to having very high solubility in an organic solvent, and has excellent thermal stability, and exhibits a good acid yield.

This application discloses a tire mold, belonging to the field of tire mold technology. The tire mold includes: a base and a tread pattern shell. The base is provided with multiple positioning elements; the tread pattern shell is provided with a positioning groove, and the tread pattern shell is installed on the positioning elements. A flow guiding gap is formed between the tread pattern shell, the positioning elements, and the base. The flow guiding gap includes a first gap. The top surface of the positioning element abuts against the bottom wall of the positioning groove, and a first gap is formed between the tread pattern shell and the mounting surface. The base is provided with a first exhaust channel, and the positioning elements are provided with a second exhaust channel. The first exhaust channel and the second exhaust channel are connected, and the flow guiding gap is connected to the second exhaust channel. The tread pattern shell includes an arc-shaped transition section, which extends from the starting position to the side where the positioning groove is located. The tangent of the arc-shaped transition section at the starting position has an angle α with a preset direction, and the value range of α is: 0°≤α≤60°. This solves the technical problems of inconvenient tread pattern replacement and easy clogging of the exhaust structure in existing tire molds.

The present invention discloses an anti-reflective coating composition, its preparation method and application, wherein the anti-reflective coating composition comprises a polymer having at least one structural unit represented by formula (1).
