A method for manufacturing a preferably asymmetrical lens element (5a) from a tempered blank (1) is characterized by: producing the lens element (5a) from a first partial volume (1a) of the tempered blank (1), whose thickness d is less than approximately 70%, preferably less than approximately 60%, particularly preferably less than approximately 50% of the thickness D of the tempered blank (1). Preferably, from a second partial volume (1b) of the tempered blank (1) at least a further lens element (5a′) is produced, wherein before the lens elements (5a, 5a′) are produced the tempered blank (1) is divided into the first and second partial volume (1a, 1b).

The invention belongs to the technical field of continuous casting, and in particular provides a method for adjusting the width of a crystallizer in an online hot state at high speed. According to the solidification and shrinkage characteristics of molten steel in the crystallizer, the present invention determines the reasonable mechanism of mold width adjustment or narrowing adjustment, deduces the adjustment limit speed of mold width or narrowing adjustment, and selects the best mold on-line heating according to actual production needs. State high-speed adjustment width parameters. The invention eliminates the air gap between the billet shell and the casting billet during the hot widening or narrowing process, so that the stress on the billet shell is low and uniform, and at the same time, the width or narrowing is improved without reducing the casting speed. speed.

The invention discloses a filter element. The filter element is placed in a filter to be used for carrying out gas-solid separation filtration and / or liquid-solid separation filtration on an object tobe filtered during use, the filter element comprises at least two filter tubes which are arranged at intervals, and tube bodies of the filter tubes are formed by shaping metal or sheet-shaped materials taking the metal as a base body in a rolled mode and carrying out sealing processing on joints; and the outer diameter of the pipe body formed by rolling is only 20 to 200 mm, preferably 20 to 90 mm, further preferably 20 to 60 mm, and further preferably 25 to 50 mm. A conventional large-diameter single-tube filter element is replaced with a bundled filter element formed by bundling a pluralityof small-diameter filter tubes, so the filter area can be remarkably increased in a limited mounting space; the filter pipe has the advantages of self-supporting property, high strength, low cost, capability of bearing high filtering temperature and small filtering resistance. Therefore, the technical problem of small filtering area of the filter element in the prior art is effectively solved.

The invention discloses a small-caliber-pipeline intensive type heat preservation device and method. The small-caliber-pipeline intensive type heat preservation device comprises a heat preservation layer and an outer protective layer frame type support. The heat preservation layer comprises first aluminum silicate fiber blankets and a composite heat preservation structure. Each first aluminum silicate fiber blanket is wrapped around a single pipeline needing heat preservation. Each first aluminum silicate fiber blanket is externally bundled with a galvanized iron wire. The composite heat preservation structure is wrapped around a row of pipelines wrapped inside the first aluminum silicate fiber blankets. The outer side of the composite heat preservation structure is bundled with iron gauze. The outer layer of the iron gauze is provided with the outer protective layer frame type support. Corrugated plates and corner wrapping plates are arranged on the outer protective layer frame type support and are fixed with self-tapping screws. The corrugated plates are arranged on the outer surface of the outer protective layer frame type support. The corner wrapping plates are arranged at the corners of the outer protective layer frame type support. By the adoption of the small-caliber-pipeline intensive type heat preservation device and method, the construction efficiency and the installation quality level can be improved, and the construction cost can be reduced.

The invention provides an automobile front suspension beam, which belongs to the technical field of automobiles. It solves the problems in the prior art that the front suspension beam is difficult to form and the effect of isolating engine vibration is low. The front suspension crossbeam of the automobile includes a crossbeam upper plate and a crossbeam lower plate. The crossbeam upper plate and the crossbeam lower plate are fixedly connected to each other to form a long hollow beam structure. The top surface of the crossbeam upper plate is fixedly connected with a suspension installation upper plate. The lower plate of the crossbeam is fixedly connected with the lower plate of the suspension installation supporting the upper plate of the suspension installation, and the upper plate of the suspension installation is fixedly connected with the lower plate of the suspension installation. The reinforcing sleeve arranged in the opposite direction is located under the upper plate of the suspension installation and is fixedly connected with the upper plate of the beam and the lower plate of the beam respectively. The invention can better isolate the vibration generated by the engine, improve the NVH performance of the automobile, and has the advantages of convenient manufacture.

The invention discloses a filter element. The filter element is placed in a filter to be used for carrying out gas-solid separation filtration and / or liquid-solid separation filtration on an object tobe filtered when in use, the filter element is provided with a plurality of filter units, the plurality of filter units are arranged on the cross section of the filter element in a concentric circular ring and / or parallel straight line manner, and each filter unit comprises one or more filter tubes which are arranged at intervals, wherein tube bodies of the filter tubes are formed by shaping metal or a sheet-shaped material taking metal as a base body in a rolled manner and performing sealing processing on joints; and the outer diameter of the tube bodies formed by rolling is only 20 to 200 mm, preferably 20 to 90 mm, further preferably 20 to 60 mm, and further preferably 25 to 50 mm. A plurality of small-diameter filter tubes are bundled, so that the filtering area can be remarkably increased in a limited mounting space; the filtering area can be further increased by reasonably arranging the arrangement mode of the filter tubes. Therefore, the technical problem of small filtering area of the filter element in the prior art is effectively solved.
