摘要:
A device and method are provided for protecting the inside of a microwave oven from food splattering during cooking. The device is made of breathable food grade paper, is a truncated cone in shape with a pleated side wall for rigidity and at least one reinforcing structure on a top surface. Top surface reinforcement may be one or more folded paper reinforcement bars or folded paper reinforcement members, shaped as circles, squares, or any other convenient shape. Reinforcement bars may be radial across the top surface or nonradial, and may be linear or curvilinear. The food shield device is made by conventional paper die stamping methods.

The invention relates to a method for continuously creating a bainite structure in a carbon steel, especially a strip steel. The method comprises the following steps: the carbon steel (1) is austenitized (3) at a temperature exceeding the austenitizing temperature; the austenitized carbon steel (1) is introduced into a bath (2) containing a quenching agent (21) in order to cool the carbon steel (1) to a temperature lying below the austenitizing temperature; the carbon steel (1) is adjusted to the transformation temperature for bainite and is maintained (13) at the transformation temperature for a certain period of time; and the carbon steel is then cooled (17). In order to further develop the method, the carbon steel (1) penetrates a bath (2) containing a quenching agent (21) until a defined percentage of the bainite structure relative to the total structure of the carbon steel (1) has formed in the bath (2) containing the quenching agent (21) following the austenitizing process, residues of the quenching agent (21) are removed from the surface of the carbon steel (1) by blowing the same off when the carbon steel (1) is discharged from the bath (2), and the remaining structure components of the carbon steel (1) are then transformed into bainite in an isothermal tempering station (13) without deflecting the carbon steel (1) at all when the same penetrates the isothermal tempering station (13).

The invention relates to a cold-rolled carbon steel comprising (in % by weight) C 0.63-0.85%, max. 0.40% Si, 0.20-0.90% Mn, max. 0.035% P, max. 0.035% S, max. 0.060% Al, max. 0.40% Cr, 0.003-0.010% N, preferably 0.005-0.008%, and a maximum of 0.12% of at least one micro-alloying element, the remainder being iron and steel production-related pollutants. Possible micro-alloying elements are Ti, Nb, V and optionally Zr. A carbon steel of the type is cold-rolled into texture-rolled strip steel with a high cold reduction degree and can be used in particular as a material for coiling springs or other components having spring properties.
